For a successful pour, it is essential for the artist to have a strong design with connected interesting shapes and at least 4 delineated values. In the photo below, Trudy transfers her value map, (large thumbnail) to her stretched watercolor paper.
Each value is masked in succession, with a separate pour for each mask. The pouring process allows for spontaneous color mixtures. Tilting the board after the pour allows the artist to “control” the direction of the color blending.
When the final pour is dry, the mask is removed, and the painting receives final touches to resolve the composition. Sometimes an over-pour is required in different areas than the initial pours. In that case, all mask is removed, and new mask is applied to areas where the initial pours are to be preserved. Removing the final mask is like unwrapping a Christmas present. By the final pour, the painting is quite obscured, and it’s always a surprise to see what lies underneath.
Because there is quite a lot of dry time between the masking and pouring process, each artist worked on at least two separate paintings simultaneously. The photo shows workshop participants pleased with their results learning the poured process:
